Thermosphere

—  The thermosphere goes from 90km to 300km.

—  It’s the hottest layer in the atmosphere.

—  The Ionosphere is found in the thermosphere.

—  Auroras(natural light display

            in the sky ) occur in this layer.

n  Curtains of light called auroras occur in this layer.

The Ionosphere is found in the thermosphere(The ionosphere is defined as the layer of the Earth's atmosphere that is ionized by solar and cosmic radiation)

n  Auroras occur in this layer.

Charged particles from space collide with atoms and molecules.

Those atoms and molecules shed this excess energy by emitting photons of light, which we see as colorful auroral displays.
